Runtime Error - ASSIGN_LENGTH_0

Hello Friends,

  Some dumps were occurred on yesterday with the sort text,

Program error: ASSIGN with length 0 in program "/SDF/SAPLSMD_E2E". by the user SM_SLM.

SM_SLM user is used in RFC(SM_SIDCLNT000_READ) connection which is from Solman to Production.

Why it has occurred ? Do we we have to do any correction in production?

I have attached DUMP file,

Please check and help me.

Regards,

Farkath C
